Tonight our ongoing look here at the undecided voters, the voters in the swing states who could very well decide this election. Tonight what they say they need to hear on tuesday evening to close the deal. Traveling through ohio rich in color this time of year and rich with vote, 18 electoral votes, no republican has won the white house without ohio. Good to be here. Reporter: We met amber singer and her children, an obama/biden sticker on her truck and the first issue she brought up. I think it should be every woman's own decision to choose what they decide to choose, not the government's choice. Reporter: And though she told me she knows mitt romney is pro-life, on this day she brought her family to hear him. And you're going to listen to mitt romney today? Yep. Reporter: Like so many families this weekend james and tiffany colver and their children picking out their pumpkins. People are now saying it all does come down to ohio. Do you sense the importance? I do, definitely. No question about it. Reporter: As we talked about what they say they need to hear tuesday night in the debate -- daddy, give me the pumpkin. Reporter: It's not the election. It's the pumpkin. It's all about what you're choosing for the pumpkin. Picking pumpkins is the easy part. They want to see a different president in this second debate. So if you were in the debate prep room this weekend with the president, what would you tell him he needs to do in this debate? I think he needs to be hard hitting on some of his issues, and I think he needs to take a more concrete stand. Reporter: Rick nolan and his wife told me they liked what they heard from mitt romney in the first debate. Do you think it'll be hard to outperform his first debate? I think he'll do just fine. Reporter: And we met these two women, brenda lovell and debbie zitelli, both voted for president obama last time but says he still needs to close the deal. Because you voted for him last time, do you still want to support him? Are you waiting to hear? I'm disappointed. I think that he made a lot of promises that haven't been kept. Reporter: But you're not sold on governor romney? No, not yet. Reporter: Wow, they're going to be looking for your name and your number. I know. I know. I know. Yeah, I know. Reporter: Her phone will be ringing tonight. That's the picture from ohio this evening and our special coverage "one on one, the candidates debate" begins 9:00 right here election headquarters. I'll be at the debate site with our jake tapper. The entire political team right heay night.
